shower/ hydrolock

[Lance B. Johnson]

Hey all,

Has anyone else had the shower cause the engine to hydrolock? We used it the first time this week and both times it filled the cylinders with water.

Whoa. I cant even picture how water could get to the cylinder from there.

I have had the same problem. I had to get another switch put in the front to make sure the shower was never on. I have not had a problem since. Make sure your shower is off. We had a switch in the back that kept getting accidently turned on. I had another switch put near the drivers seat so it would take two to turn it on. I believe it is both the case of hydrolock as well has drainage of the battery that causes the problem.

PM me if you want to talk further about it.

sure, under pressure it pushed water into the engine cooling system, up to the point where it began filling the exhaust manifolds and then draining through the exhaust.

This doesn't make a lot of sense to me. The shower is installed on a separate part of the engine than the cylinders..... the cooling part that goes thru the water pump & exhaust. If the cooling system were backed up, then it would not suck fresh water from the lake, and probably over heat. But there is no way I'm aware of for water to get from the cooling system to the cylinders...... unless a head gasket is bad, or a cracked head.

Is your shower on & spraying right at your air cleaner?

The shower switch should be off & the nozzle off.

I studied the system for awhile and if the shower head is turned off, but the pump is left on the pump should build pressure and then cut out right? Ours is not doing this. When the shower head is off, the pump initially shuts off. After about 30 seconds the pump cycles on again and it continues to repeat cycling on and off.

On a side note, I am sure that the shower is causing this as we just got home from the lake house after a two week stint. The boat performed perfectly the entire time never showing any signs of a blown head gasket or other failure. Besides I doubt I blew both head gaskets at the same time on an engine that has 230 hours on it. I mean I am very aware that it is possible, but unlikely on an engine that did not overheat.

The engine locked up exactly two times, right after the girls used the shower. And we have never used the shower before.

Oh and there is one way for water to get in to the cylinders via the cooling system and that is through the exhaust manifolds.

leaving a valve open to filling, gotcha...
